Abstract

The natural supply of land resources is limited, but the economic supply may change along with social and economic development, and its size is decided bye nature and social and economic body conditions. When the supplying ability of land resources threatens the development of society and the conflict between people and land becomes tense, it forced people to improve land utilization and to increase the effective supply of land resources. The paper made an overall consideration on the characteristics of the irrigated farming and the frail ecological environment in Fuhai County, Altay Area, Xinjiang Uigur Autonomous Region and explored land arrangement planning as well as water resource planning and environmental protection. The paper evaluated natural resources, land utilization and water resource of the case study areas and focused on the spatio-temporal balance between the utilization of water and land resources. In the end the paper a feasible plan was made out for the land arrangement project.  相似文献

Abstract

This paper studies factors influencing rural-urban labor migration in China, particularly the implementation of rural cooperative medical insurance (RCMI) in the year 2003. With the support of data analysis from the year 2000, 2004 and 2006, clear linear correlations are found between gender, income, health condition and rural-urban labor flow, whereas the impact of education and employment status are more complicated. More importantly, results from regression show that the establishment of RCMI in countryside of China not only inhibits rural residents from seeking employment outside the village, but also pulls back rural people who have already worked in cities. When regional dimension is concerned, the pure composite effect of RCMI on rural labor flow is less significant in coastal areas with better economic performance and medical service.  相似文献

The coronavirus disease 2019 (COVID-19) pandemic is still spreading all over the world. Although China quickly brought the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) under control in 2020, sporadic outbreaks have recurred from time to time. Outbreaks since June 2020 have suggested that the imported cold food supply chain is a major cause for the recurrence and spread of COVID-19. Here we review recurrent outbreaks in China from June 2020 to March 2021, and we analyse the main causes for recurrence and transmission by the supply of imported cold food from port to fork. Contaminated cold food or food packaging material can transmit the virus through ‘person-to-thing-to-person’, by contrast with the classical ‘person-to-person’ pathway. We decribe safety precautions for the food system, operating environment and people along the cold chain logistics. Surface disinfection and nucleic acid inspection are needed in each stage of the logistics of imported cold food supply.
